Hi, i also have an issue with this chip on a custom Board connected to
an phyCORE-AM3352 (Phytec).
My schematic is attached. The IOUSBEN signals are connected to some
GPIOs.
My board file looks like this:
/* pinmux for usb0 drvvbus */
static struct pinmux_config usb0_pin_mux[] = {
{"usb0_drvvbus.usb0_drvvbus", OMAP_MUX_MODE0 | AM33XX_PIN_OUTPUT},
{NULL, 0},
};
/* pinmux for usb1 drvvbus */
static struct pinmux_config usb1_pin_mux[] = {
{"gpmc_ad8.gpio0_22", OMAP_MUX_MODE7 | AM33XX_PULL_ENBL |
AM33XX_PIN_OUTPUT_PULLUP},
{"gpmc_ad9.gpio0_23", OMAP_MUX_MODE7 | AM33XX_PULL_ENBL |
AM33XX_PIN_OUTPUT_PULLUP},
{"lcd_vsync.gpio2_22", OMAP_MUX_MODE7 | AM33XX_PULL_ENBL |
AM33XX_PIN_OUTPUT_PULLUP},
{"lcd_ac_bias_en.gpio2_25", OMAP_MUX_MODE7 | AM33XX_PULL_ENBL |
AM33XX_PIN_OUTPUT_PULLUP},
{"usb1_drvvbus.usb1_drvvbus", OMAP_MUX_MODE0 | AM33XX_PIN_OUTPUT},
{NULL, 0},
};
static void usb0_init(void)
{
setup_pin_mux(usb0_pin_mux);
return;
}
static void usb1_init(void)
{
setup_pin_mux(usb1_pin_mux);
return;
}
static struct omap_musb_board_data musb_board_data = {
.interface_type = MUSB_INTERFACE_ULPI,
/*
* mode[0:3] = USB0PORT's mode
* mode[4:7] = USB1PORT's mode
* PCM051 has USB0 in OTG mode and USB1 in host mode.
*/
.mode = (MUSB_HOST << 4) | MUSB_OTG,
.power = 500,
.instances = 1,
};
The inits are called correctly.
First i get this message polling:
ti81xx_interrupt 1146: VBUS error workaround (delay coming)
Then i used this patch:
6378.0001-Revert-usb-musb-ti81xx-fix-for-handling-vbus-error.zip
from Bin Liu in this Forum. It stopped polling but is still in the dmesg
log.
Then I also tried to not use the USB_DRVV Pin and connected the Reset
Pin directly to 3.3V and tried this hack:
diff --git a/arch/arm/mach-omap2/omap_phy_internal.c

}
} else {
Nothing helped. I disabled the hack and soldered all changes back. My
Board looks like the schematic.

Can anybody help me?
At boot time USB_DRVV changed shortly to high and then back to low.
USB_VBUS is already high at this time and goes low when the USB_DRVV
signal went low.
After this VBUS is going back to high. I can't figue my issue out.
I think my schematics are ok.
MMC2:
Hi,
I have also an issue with mmc2 @ an AM3352 phyCore and a custom Board.
My muxing and initialisation looks like this:
static struct omap2_hsmmc_info am335x_mmc[] __initdata = {
{
.mmc = 1,
.caps = MMC_CAP_4_BIT_DATA,
.gpio_cd = GPIO_TO_PIN(0, 6),
.gpio_wp = -EINVAL,
.ocr_mask = MMC_VDD_32_33 | MMC_VDD_33_34, /* 3V3 */
},
{
.mmc = 2,
.name = "EX_SD",
.caps = MMC_CAP_4_BIT_DATA,
.nonremovable = false,
.gpio_cd = GPIO_TO_PIN(3, 16),
.gpio_wp = -EINVAL,
.ocr_mask = MMC_VDD_32_33 | MMC_VDD_33_34, /* 3V3 */
},
{
.mmc = 0, /* will be set at runtime */
},
{} /* Terminator */
};
/* Module pin mux for mmc0 */
static struct pinmux_config mmc0_pin_mux[] = {
{"mmc0_dat3.mmc0_dat3", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT_PULLUP},
{"mmc0_dat2.mmc0_dat2", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT_PULLUP},
{"mmc0_dat1.mmc0_dat1", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT_PULLUP},
{"mmc0_dat0.mmc0_dat0", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT_PULLUP},
{"mmc0_clk.mmc0_clk", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT_PULLUP},
{"mmc0_cmd.mmc0_cmd", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT_PULLUP},
{"spi0_cs1.mmc0_sdcd", OMAP_MUX_MODE7 | AM33XX_PIN_INPUT_PULLUP},
{NULL, 0},
};
/* Module pin mux for mmc2 */
static struct pinmux_config mmc2_pin_mux[] = {
{"gpmc_ad12.mmc2_dat0", OMAP_MUX_MODE3 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_ad13.mmc2_dat1", OMAP_MUX_MODE3 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_ad14.mmc2_dat2", OMAP_MUX_MODE3 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_ad15.mmc2_dat3", OMAP_MUX_MODE3 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_csn3.mmc2_cmd", OMAP_MUX_MODE3 | AM33XX_PIN_INPUT_PULLUP},
{"mii1_rxd1.mmc2_clk", OMAP_MUX_MODE6 | AM33XX_PIN_INPUT_PULLUP},
{"mcasp0_axr0.mmc2_sdcd", OMAP_MUX_MODE4 | AM33XX_PIN_INPUT_PULLUP},
{NULL, 0},
};
static void mmc0_init(void)
{
setup_pin_mux(mmc0_pin_mux);
setup_pin_mux(mmc2_pin_mux);
omap2_hsmmc_init(am335x_mmc);
return;
}
The inti is called @ boot time.
@ Kernel Booting mmc0 works like a charm. The Kernel and Barebox is
booting from it.
But mmc2 doesn't work. I looked at the cmd and clk line. cmd line is @
everytime high due to a 10k Pullup in the Schematic.
Unfortunatly the clk line is @ everytime low. Nothing happens there. And
after booting only mmc0 is available. Where is the Problem?? clk is
directly connected to the SD-Card without any pullup/down. I tested it
with plugging in an SD-Card before and after Kernel booting... nothing.
:-(
Can somebody help me?
Tut mir leid das ich hier alles auf Englisch geposted habe. Wollte nur
nicht nochmal alles schreiben. Hab halt auch bereits im TI Forum und im
Cypress Forum angefragt. Vielleicht kann ja hier jemand helfen.
